(Table 1) Thermoluminescence datings of glacial deposits from several sites in Schleswig-Holstein, north Germany

First thermoluminescence (TL) datings of glacial deposits from several well-known sites in northwest Germany (Schleswig-Holstein) indicate a possible Middle Weichselian Glaciation in this region. The TL dates obtained imply an ice sheet at about 70-40 ka B.P. here, whose presence in this part of Europe has not been previously considered. The reliability of the TL dates was cross-checked on different lithologies; the dating was performed in two independent laboratories. These dates and their interpretations, however, must still be confirmed both geologically and paleontologically on suitable sites where glacial sediments are sandwiched between Eemian deposits and interstadial deposits older than the Late Weichselian.

针对德国西北部（石勒苏益格-荷尔斯泰因州）多处知名点位的冰川沉积开展的首次热释光（thermoluminescence, TL）测年研究显示，该区域可能存在中魏克塞尔冰期（Middle Weichselian Glaciation）活动。本次获得的TL测年结果表明，该区域在距今7万至4万年左右存在冰盖，而此前学界并未考虑欧洲该区域曾有冰盖分布。为验证TL测年结果的可靠性，本研究针对不同岩性开展了交叉校验，且测年实验分别于两家独立实验室完成。不过，上述测年结果及其相关解释仍需在合适点位开展地质与古生物学验证：这些点位的冰川沉积需夹于埃姆间冰期沉积（Eemian deposits）与早于晚魏克塞尔冰期（Late Weichselian）的间冰阶沉积之间。
